Method for program revise of an IC smartcard system

摘要

A method for modifying program in EEPROM of an IC smart card system. First, save the operating program of IC smart card system in a ROM, the operating program has a function of Add Command. Next, increase the content of the command code before formatting the IC smart card, wherein the increased command code and the actual content are saved in an EEPROM. Then, formatting the IC smart card to define the file segment of the EEPROM, and finally input personal data in the IC card to complete the card activating procedure. By using the program modification method, the time for the IC card producing is reduced and the efficiency is improved when there are small changes of the functions of the IC card.
